Asus PCIe GEN2 SATA6G expansion card

CrystalDisk, ATTO & File transfer

CrystalDiskMark is a free utility maintained by Japanese company Crystal Dew World. CrystalDiskMark evaluates the performance of your hard drives based on two tests – a sequential read/write test and a random read/write test. You can select the drive to test, the number of test and the size of the data to test which can be 50MB, 100MB, 500MB and 1000MB. The results displayed below have been conducted using 5 rounds of the 500MB test.

ATTO Disk Benchmark
ATTO Disk Benchmark may be one of the oldest hard disk benchmark utilities still in service, but many would argue that it still remains the best. Unlike HDTune Pro and many other benchmarking utilities, ATTO can be configured to write up to 256MB of data to the disk in file sizes varying from 5KB to 8MB. This is especially useful for SSD drives and indeed RAID configurations where performance can be heavily reliant on the cluster size of the disk. All tests were run with the default settings of 0.5KB through 8192KB transfer sizes with the total length of 256MB. For clearer comparative purposes, the key stages of the benchmark are included in the graphs below:

Dummy File Creation
When performing manual "file copy" benchmarks, the performance of the drive that the files are being copied from can directly and negatively affect the results of the drive they are being copied to. This is something that needs to be taken into consideration when benchmarking high performance hard disks such as the OCZ Vertex SSD as it's performance easily exceeds that of a standard hard disk. Therefore, to test the write performance of each storage device a freeware utility called Dummy File Creator was used to generate files directly to each of the hard disks. The first 16GB benchmark writes a collection of files ranging in size from 1GB to 100KB, whereas the 100GB benchmark writes a single file of exactly that size to the disk.
Results Analysis
 Across the range of results, you can see that there are improvements at all stages of the benchmarks. Both read and write speeds are improved and this is exemplified by the 'real world' testing of writing large files to the hard disk where the time was significantly cut when comparing like for like. Overall we can see a 10%+ improvement with all the benchmarks run when the Asus PCIe GEN2 SATA6G card is used.
Let's take a look at what Asus claim is the jewel in the 6G controllers crown - burst speed...

Be nice to see if this affected Crossfire or SLI performance as the Gigabyte solution does.

Good review as usual though Rich Quote

It all depends on how many slots you have available. With P55 having 16 lanes available, taking 4 up with the SATA6 card will have some effect on SLI performance, if indeed you have a spare slot to begin with on P55. X58 however has more lanes so SLI/xfire performance will not be affected unless you intend on running 2x dual GPU cards that require the full 16 lanes or indeed triSLI/crossfireX.Quote

Amazes me that the population on a close up look is for USB. The parts are ofc missing.

I did think, looking at another manufacturer, that the un-soldered bits were for eSATA of sorts. Apparently not.

Nice review.

Not a bad price tbh. Online stores may massage that a little. Wouldn't be too suprized if a fully populated version comes out afterwards. They're *******s for doing that. Bring out the lesser - get u to buy it - then out comes the trump card.Quote

Great idea for those on older tech but still want the speed. Once some drives come out at a decent price, or I pick up a 6G capable SSD I may grab this too Quote

I'd be interested to see this card with a RAID setup of SSD's.Quote
